Application filed February a7, 1919. Serial No. 279,481.

To all whom it may concern Be it known that l, WILLIAM C. REUTTER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Wing Controls for Aeroplanes, of which the following is a specification.

My invention relates to a new and useful improvement in wing controls for aeroplanes, and has for its object'to provide eifective means under the control of the aviator, whereby lifting power may be applied to the outer ends of the wings for overcoming the tendency of the machine to upset.

With this end in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how tomake and use the same, I will describe its construction in detail referring by numerals to the accompanying drawing forming a part of this application, in

valve 8, to the operating lever 9 of which is pivoted the rod 10, which latter passes within easy reach of the aviator so that by the moving of this rod inone direction or the other, one valve will be opened, the other closed,, or by brin ing to the center both valves. will be close( i.

11 and 12 represent two curved planes which are secured to the wings adjacent the outlets of the nozzles in such manner that air issuing under pressure from the nozzle will impinge against said curved planes and be deflected downward, the operation of which will tend to force the curved plane thus acted upon and the wing to which it is attached upward.

When an aeroplane is equipped with my lmprovement it is within the power of the aviator, should his machine tip sidewise to a dangerous degree to exert a lifting force upon the lowered wing thereby righting the machine; as this can be done upon either side of the machine it follows that the aviator can avoid the serious accidents-which so often take place.

The fact that the valves are placed at the outer ends of the pipes 2 and 3 permits the immediate application of air under pressure from the blower upon the curved planes, as it is intended that the blowershall be constantly in operation while the machine is flying, the lifting force can be applied instantaneously by the aviator to either end of the machine.

In Fig. 2, I have shown another form of my invention in which the valve 8 carries the nozzle 13 curved downward and this nozzle may be so formed as to have three outlets as shown. When compressed air is forced through and from this nozzle its action upon the atmosphere will' produce reaction which will give a lifting tendency, producing the same effect as that described in connection with the impinging of the air upon the curved planes.

While I have shown my invention as applied to the lower wings of a biplane it is obvious that it maybe applied to theupper wings and that it will operate with equal facility upon the wings of a monoplane or other flying machines.

' Of course I do not wish to be limited to. the exact details of construction as herein shown, asthese may be varied within the limits of the appended claims without departin from the spirit of my invention.

Having thus fully described my invention what I claim as new and'useful is 1'. In combination with the wings of a flying machine, curved planes attached to the outer en'ds of the wings, nozzles disposed adjacent said curved planes, valves located adjacent the nozzles, means for supplying air under pressure, pipes leading from said means to the valves, means connectingthe operating handles ofthe valves together, said last named means being in easy reach of the operator of the machine.

2. In an aeroplane t wo curved planes attached to the outer portion of the Wings of said machine, means carried by the aeroplane for supplying air pressure, two pipes leading from said means and terminating in the nozzles adjacent said curved planes, valves connecting the pipes and nozzles, and means for operating said valves in unison.

3. In an aeroplane, means for supplying air under pressure, pipes leading from said means, valves for controlling the flow of air through said pipes, a rod connecting the valves for operating the latter in unison, nozzles projecting from the valves, and curved planes secured to the outer portion of the Wings adjacent the nozzles.

In testimony whereof, I have hereunto affixed my signature.

WILLIAM C. REUTTER.
